Fifth generation 1957-1959
1957
This year, Chrysler cars were redesigned with Virgil Exner's "Forward Look" at the cost of $300 million. The 1957 New Yorker had a powerful 392 cu in (6.4 L) Hemi V8 engine rated at 325 hp (242 kW). This stylish car sold well with 10,948 built, but only 1,049 convertible models. The 1957 models also came with the TorqueFlite 3-speed automatic transmission and a Torsion bar suspension called Torsion-Aire that gave smoother handling and ride quality to the car. The New Yorker also sported fins that swept up from just behind the front doors.
Early model year production had single headlamps with quad headlamps optional where state regulations permitted them. The single headlamps were dropped later in the year.
1958
Forward Look remains intact but with new body-side trim, shrunken taillights and 345 hp (257 kW). The convertible model was still available, with only 666 made and only 15 working convertibles are known to still exist in 2008. Sales were steady, but decreased from last year due to The Recession of 1958. The car's reputation was also tainted due to rust problems caused by rushed production and testing.
The biggest news from Chrysler in 1958 was the introduction of a cruise control system called "Auto-Pilot".
1959
The New Yorkers this year had a new 413 cu in (6.8 L) 350 hp (260 kW) Golden Lion V8, new tailfins, new front end, and no Hemi. The FirePower (1G) Hemi ended production and was replaced by the less expensive and lighter wedge head engine. The Hemi would never return to the New Yorker and slowly ended its image as a performance car and re-branded it as a luxury car. The Hemi engine itself would not return to Mopar cars until 1964 with the second generation 426 Hemi.
